Getting Started with Python on the Raspberry Pi?

The Raspberry Pi is a versatile, low-cost computer that lets you learn to code in Python and work on electronics projects. With just a few steps, you can set up Python and start building programs on your Raspberry Pi.

Getting Started with Python on the Raspberry Pi?

The Raspberry Pi is a series of affordable, single-board computers developed by the Raspberry Pi Foundation. Some key facts about the Pi:

  • costs just $35 – $75 depending on the model
  • runs Linux-based operating systems like Raspberry Pi OS
  • has USB ports, GPIO pins, camera/display interfaces
  • HDMI port to connect monitors and TVs
  • designed to promote teaching of computer science and programming

There have been several revisions of the Pi hardware over the years featuring faster processors and more memory capacity. The Raspberry Pi 4 Model B is the latest and most powerful.

Getting Set Up with Raspberry Pi OS

To start programming Python on a Raspberry Pi, you’ll need to get your Pi set up with an operating system. The official Raspberry Pi OS (previously called Raspbian) offers the easiest setup process:

  1. Install Raspberry Pi Imager on your computer to write the OS image to a microSD card.
  2. Download the Raspberry Pi OS image from the Raspberry Pi website. The 32-bit version with desktop is recommended.
  3. Insert your microSD card into your computer. Launch Raspberry Pi Imager and install Raspberry Pi OS to the SD card.
  4. Insert the microSD card with Raspberry Pi OS into your Pi. Connect a monitor, keyboard, and mouse. Apply power to boot up the Pi.
  5. Resize the filesystem in the raspi-config tool for better storage capacity.

That covers the basic OS setup! Raspberry Pi OS comes pre-loaded with Python and everything you need to start coding.

Programming in Python on Raspberry Pi

Python is considered the best programming language to learn first due to its straightforward syntax that reads like English. As an interpreted language, Python doesn’t need to compile source code before execution. This allows for rapid prototyping and development.

Some reasons why Python is the ideal choice for learning on the Raspberry Pi:

  • Python has a shallow learning curve while still being very capable for complex programs.
  • It comes pre-installed on Raspbian/Raspberry Pi OS.
  • Many Raspberry Pi add-ons feature Python APIs/libraries for simplified control in your own programs.
  • The Python Package Index (PyPI) contains thousands of modules extending functionality.

Let’s walk through some steps to start programming Python scripts:

  1. Launch the desktop terminal/command line. The terminal gives access to the Linux shell to run commands and programs.
  2. Use nano, vim or any text editor to create a new Python script. For example, my_script.py with print statements.
  3. Save the script and run it with the python command. Here we run a script named hello.py:

python hello.py

That’s really all there is to running your first Python program on a Raspberry Pi! Now you can develop any kind of application from games to web servers.

Python IDEs for Raspberry Pi

While it’s possible to write Python on the Raspberry Pi using only a simple text editor, an integrated development environment (IDE) makes programming easier. IDEs come packed full of features to accelerate development like syntax highlighting, auto-indentation, and debugging capabilities.

Some IDEs commonly used for Python programming on the Raspberry Pi:

  • Thonny Python – Thonny comes pre-installed on Raspberry Pi OS. It’s tailored specially for education and beginner programmers.
  • Geany – Geany is also pre-installed and good for quick edits with its fast loading times.
  • Pycharm – While not included by default, Pycharm offers advanced capabilities for larger projects. You can install it through Raspberry Pi’s preference for IDEs.

When starting out, Thonny strikes the best balance of capabilities while staying simple to operate. As your skills grow, check out other Python code editors to suit your needs.

Getting Help with Python

Don’t worry about memorizing every Python command and syntax just yet. As a beginner, focus more on understanding programming concepts first.

Refer the official Python 3 documentation and learn more from these Raspberry Pi resources:

  • Raspberry Pi Python tutorials – Teach beginner and advanced Python topics with example code. Also covers installing modules.
  • MagPi magazine eBook – Free book covering image processing, Minecraft automation, Internet of Things projects, and machine learning algorithms examples all on the Raspberry Pi using Python.
  • Raspberry Pi forum – Ask questions and get troubleshooting help from Raspberry Pi’s large community.
  • Stack Overflow – As you gain more programming experience, Stack Overflow has detailed answers to almost any coding problem encountered.

Automating Tasks with Python Scripts

Once comfortable with Python syntax, try creating scripts to automate tasks and save time. Python excels as a scripting language to connect other programs.

Here are some ideas for handy Raspberry Pi Python scripts:

  • Automatically back up files to cloud storage
  • Schedule scripts to run with cron
  • Pull data from an API
  • Control GPIO pins to blink LEDs
  • Run equipment on a schedule
  • Share a webcam or weather station online
  • Send notifications when something occurs
  • Create a Python script GUI

As your programs grow more advanced, look into Python web frameworks like Django and Flask. Before you know it, you’ll be serving web content and hosting sites from home!
